This is a real shame for the illumos community.
We switched from Solaris on SPARC hardware to OmniOS on x86 a few years ago because it was, for us, a natural successor to Solaris, commercially supported and with all the same cool features we came to know and love. (Dtrace, ZFS, Crossbow, SMF, containers to name a few).
Add to that the support for KVM and, more recently, Linux-emulated (lx) zones and it's going to be hard to find a replacement we're happy with.
OpenIndiana is still an option if some of the OmniOS innovations can be back-ported.
